In addition to traditional approaches, a new option for the management of patients on dialysis includes the use of a potassium binder, sodium zirconium cyclosilicate (SZC). We evaluated the effect and safety of SZC in patients with chronic PD. Objective: To present a case series that illustrates the real-world use of new potassium-binders in hyperkalemic patients on peritoneal dialysis. Methods: This case series collected 9 patients on PD with baseline potassium values > 5.5 mmol/l and who were treated with SZC 5 g once a day. Data were collected at baseline and at 1, 2, and 3 months after initiation of treatment. Results: The median age of patients was 64.5 years and the median duration of observation was 90 ± 5 days. It was observed that median serum potassium decreased (5.8 mmol/l at baseline with a range of 5.8 mmol/L - 6.8 mmol/L versus 4.5 in the third month with a range of 3.6 mmol/L - 5.3 mmol/L) after SZC treatment. Adverse events were observed in 2 (22.2%). The unique adverse event was constipation and presented in 2 patients (22.2%). Constipation was mild and transient during the observation period. No adverse events of special interest were reported. Conclusion: Normokalemia was established and maintained in this series of patients treated with SZC. No episodes of hyper- or hypo-kalemia were observed. SCZ had a good safety profile and was well tolerated over 3 months.展开更多

Although it has many advantages, it also has a number of complications, such as peritoneo-vaginal leakage of dialysate. Cases Reports: Three male patients, aged 70, 50 and 77 respectively, with ESKD were placed on PD. All three patients presented with inadequate drainage and the progressive appearance of bilateral hydrocele, which occurred one year (late leakage), two and four days (early leakage) respectively after the initiation of exchanges. The etiological investigation led to the conclusion of a peritoneo-vaginal leak associated with an inguinal hernia in only one case. The two cases of early leakage were treated by temporary suspension of PD, with a good response in one case and failure in the second, leading to hisdefinitive transfer to hemodialysis (HD);however, the hernia repair enabled immediate resumption of PD in the third patient. Discussion and Conclusion: Peritoneo-vaginal leakage is a rare mechanical complication in PD. The clinical examination plays an essential role in confirming the diagnosis and in the therapeutic decision. If the diagnosis is uncertain, or if there is a clinical need to show the anatomy of the leak, an imaging approach becomes desirable. This complication should not prevent the progression of PD in the management of patients with ESKD.展开更多

METHODS: One hundred and twelve patients undergoing PD participated in the study. The gastrointestinal symptom rating scale was used for measuring GI symptoms. Information on age, height, weight, body mass index, disease leading to chronic renal failure, history of corticosteroid therapy, presence of predialytic GI symptoms, daily dosage of pills, and duration, type and daily dialysate volume of PD was obtained by interviewing patients and/or reviewing the medical records. Hemoglobin, albumin and Kt/V data were obtained from follow-up database. We used multiple regression analysis with stepwise backward variable selection to test for factors predicting GSRS scores with significance level of selection entry at 0.05 and selection of stay at 0.10. RESULTS: The prevalence of eating dysfunction, reflux and indigestion in the PD patients was 44.2%, 32.7%,32.7%, respectively. A history of corticosteroid therapy (b = 8.93, P < 0.001) and all pills daily intake (b = 0.16, P = 0.007) were positively correlated to GI symptoms, while residual renal Kt/V (b =-3.47, P = 0.009) was negatively correlated to GI symptoms. Other factors were proven to be not associated with GI symptoms, with P > 0.05. CONCLUSION: Eating dysfunction, reflux and indigestion were common in PD patients. Daily dosage of pills and corticosteroid history predicted GI symptoms, while residual renal function prevented them.展开更多

Although quality standards demand an infection rate 〈 0.67 episodes/patient/year on dialy-sis, the reported overall rate of PD associated infection is 0.24-1.66 episodes/patient/year. It is estimated that for every 0.5-per-year increase in peritonitis rate, the risk of death increases by 4% and 18% of the episodes resulted in removal of the PD catheter and 3.5% re-sulted in death. Improved diagnosis, increased aware-ness of causative agents in addition to other measures will facilitate prompt management of PD associated infection and salvage of PD modality. The aims of this review are to determine the magnitude of the infection problem, identify possible risk factors and provide an update on the diagnosis and management of PD as-sociated infection. Gram-positive cocci such as Staphy-lococcus epidermidis , other coagulase negative staphy-lococcoci, and Staphylococcus aureus (S. aureus ) are the most frequent aetiological agents of PD-associated peritonitis worldwide. Empiric antibiotic therapy must cover both gram-positive and gram-negative organ-isms. However, use of systemic vancomycin and cip-rofoxacin administration for example, is a simple and efficient first-line protocol antibiotic therapy for PD peritonitis - success rate of 77%. However, for fungal PD peritonitis, it is now standard practice to remove PD catheters in addition to antifungal treatment for a minimum of 3 wk and subsequent transfer to hemodi-alysis. To prevent PD associated infections, prophylactic antibiotic administration before catheter placement, adequate patient training, exit-site care, and treatment for S. aureus nasal carriage should be employed. Mupi-rocin treatment can reduce the risk of exit site infection by 46% but it cannot decrease the risk of peritonitis due to all organisms.展开更多

Recent studies suggest that congestion has the ability ofmodulating the interactions between the kidney and the heart in this setting. Peritoneal dialysis (PD) is a home-based therapeutic modality that is not only offered to patients with end-stage renal disease to provide solute clearance and ultrafltration, but it has also been used in patients with refractory heart failure and fuid overload to help optimize volume status. Several uncontrolled studies and case series have so far evaluated the role of PD in management of hypervolemia for patients with heart failure. They have generally reported favorable results in this setting. However, the data on the outcomes of patients with end-stage renal disease and concomitant heart failure is mixed, and the proposed theoretical advantages of PD might not translate into improvedclinical endpoints. Congestion is prevalent in this patient population and has a signifcant effect on their survival. As studies suggest that a significant subset of patients with end-stage renal disease who receive PD therapy are hypervolemic, suboptimal management of congestion could at least in part explain these conficting results. PD is a highly fexible therapeutic modality and the choice oftechniques, regimens, and solutions can affect its ability for optimization of fluid status. This article provides an overview of the currently available data on the role and clinical relevance of congestion in patients with cardiorenal syndrome and reviews potential options to enhance decongestion in these patients.展开更多

These anatomical and functional changes predispose to complications like peritonitis,encapsulating peritoneal sclerosis and ultrafiltration failure. In recent years, "biocompatible" and glucosesparing PD regimens have been developed to minimize damage to the peritoneal membrane. Can the use of these more expensive solutions be justified on current evidence? In this review of the literature, we explore how we may individualize the prescription of biocompatible PD fluid.展开更多
文摘BACKGROUND Peritoneal dialysis(PD)is an important renal replacement therapy in patients with end-stage renal disease.PD catheters remain the lifeline for patients undergoing PD.The catheter technique survival rate is considered a core PD outcome domain.CASE SUMMARY The PD catheter spontaneously dislodged in a patient undergoing PD during regular fluid exchange without pain.Abdominal computed tomography showed a tunnel infection.A double-cuff straight Tenckhoff catheter had been inserted using the Seldinger technique.Before this incident,the patient had a history of tunnel infections.We speculate that recurrent tunnel infections and catheter insertion using the Seldinger technique may have led to catheter dislodgement.CONCLUSION The present case suggests that clinicians should more rigorously assess the persistence of catheter-related infections concerning the potential complications arising from catheter dislodgement associated with the Seldinger technique.
文摘The risk of peritonitis complications in continuous ambulatory peritoneal dialysis(CAPD)can be prevented or reduced by providing proper education and continuous monitoring.Telemedicine and telemonitoring are methods that enable remote monitoring and patient care.This study aimed to determine the success and factors affecting telemonitoring in CAPD patient care.This study is a scoping review(ScR)using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses-ScR method.Article searches were carried out on ProQuest,PubMed,and ScienceDirect with a time range of 2018-2023.Data extraction was performed regarding knowledge level,quality of life,clinical outcomes(peritonitis),and risk of hospitalization.Of the 12 articles and studies included,6 articles were related to the effect of telemonitoring on CAPD patient outcomes,and 6 articles were associated with the effect of education on CAPD patient outcomes.Education provided to patients can improve patient understanding of therapeutic modalities for renal disorders,reduce the potential for peritonitis and dialysis complications,and improve the quality of life of patients with CAPD.CAPD patients who received telemonitoring had a better quality of life,good clinical outcomes,and a lower risk of hospitalization than those who did not receive telemonitoring and had fewer health-care visits.In summary,the implementation of telemonitoring and education in chronic kidney disease patients with CAPD modality therapy has been proven effective in improving quality of life and reducing dialysis-related risks.
文摘Peritoneal dialysis(PD)is a commonly used modality for kidney replacement therapy for patients with end-stage kidney disease(ESKD).PD offers many benefits,including home-based care,greater flexibility,and preservation of residual kidney function compared to in-center hemodialysis.Nonetheless,patients undergoing PD often face significant challenges,including systemic inflammation,PD-related peritonitis,metabolic disorders,and cardiovascular issues that can negatively affect their quality of life and treatment outcomes.Recent studies have demonstrated the crucial role of the gut microbiome in overall health and treatment results,supporting the hypothesis that probiotics may bring potential benefits to the general population of ESKD patients.However,specific data on probiotic use in PD patients are limited.This opinion review aims to summarize the current knowledge on the relationship between PD and the gut microbiome and offers a novel perspective by specifically exploring how probiotic interventions could improve the outcomes of PD treatment.The review also outlines some clinical data supporting the effectiveness of probiotics in patients undergoing PD and considers the difficulties and restrictions in their application.Based on the current knowledge gaps,this study seeks to explore future research directions and their implications for clinical practice.
文摘Background: Patients with end-stage kidney disease (ESKD) on maintenance dialysis have a high risk of developing hyperkalemia. In addition to traditional approaches, a new option for the management of patients on dialysis includes the use of a potassium binder, sodium zirconium cyclosilicate (SZC). We evaluated the effect and safety of SZC in patients with chronic PD. Objective: To present a case series that illustrates the real-world use of new potassium-binders in hyperkalemic patients on peritoneal dialysis. Methods: This case series collected 9 patients on PD with baseline potassium values > 5.5 mmol/l and who were treated with SZC 5 g once a day. Data were collected at baseline and at 1, 2, and 3 months after initiation of treatment. Results: The median age of patients was 64.5 years and the median duration of observation was 90 ± 5 days. It was observed that median serum potassium decreased (5.8 mmol/l at baseline with a range of 5.8 mmol/L - 6.8 mmol/L versus 4.5 in the third month with a range of 3.6 mmol/L - 5.3 mmol/L) after SZC treatment. Adverse events were observed in 2 (22.2%). The unique adverse event was constipation and presented in 2 patients (22.2%). Constipation was mild and transient during the observation period. No adverse events of special interest were reported. Conclusion: Normokalemia was established and maintained in this series of patients treated with SZC. No episodes of hyper- or hypo-kalemia were observed. SCZ had a good safety profile and was well tolerated over 3 months.
文摘Introduction: Peritoneal dialysis (PD) is an extra-renal purification technique indicated for patients with end-stage kidney disease (ESKD). Although it has many advantages, it also has a number of complications, such as peritoneo-vaginal leakage of dialysate. Cases Reports: Three male patients, aged 70, 50 and 77 respectively, with ESKD were placed on PD. All three patients presented with inadequate drainage and the progressive appearance of bilateral hydrocele, which occurred one year (late leakage), two and four days (early leakage) respectively after the initiation of exchanges. The etiological investigation led to the conclusion of a peritoneo-vaginal leak associated with an inguinal hernia in only one case. The two cases of early leakage were treated by temporary suspension of PD, with a good response in one case and failure in the second, leading to hisdefinitive transfer to hemodialysis (HD);however, the hernia repair enabled immediate resumption of PD in the third patient. Discussion and Conclusion: Peritoneo-vaginal leakage is a rare mechanical complication in PD. The clinical examination plays an essential role in confirming the diagnosis and in the therapeutic decision. If the diagnosis is uncertain, or if there is a clinical need to show the anatomy of the leak, an imaging approach becomes desirable. This complication should not prevent the progression of PD in the management of patients with ESKD.
文摘Objective:To study the prevalence of anemia,the proportion of hemoglobin(Hb)levels,the treatment methods,and the influencing factors of Hb levels in maintenance hemodialysis(MHD)and peritoneal dialysis patients.Methods:In this study,602 patients with maintenance hemodialysis and continuous ambulatory peritoneal dialysis were enrolled from December 2020 to December 2022 in our hospital,and their medical records were collected and summarized.The main contents included the patient’s gender,age,primary disease,dialysis duration,dialysis method,the use of erythropoietic stimulating agents(ESA),intravenous iron,and laboratory tests.A Hb index exceeding 110 g/L was set as the standard for the prevalence of anemia.Results:The rate of anemia in patients undergoing blood purification was 83%.The proportion of ESA use was 84.1%,and the proportion of iron use was 76.7%,of which the proportion of intravenous iron used was 17.0%,and the proportion of folic acid used was 28.3%.Conclusion:The incidence of anemia in MHD patients was relatively high,with a low proportion of patients reaching the standard Hb levels.Risk factors include albumin(ALB)levels,iron storage,white blood cells,C-reactive protein,cholesterol,etc.Nutritional support,iron supplementation,and prevention of micro-inflammatory reactions can effectively promote the improvement of Hb indicators in dialysis patients to prevent anemia.
文摘BACKGROUND Neisseria mucosa is a gram negative diplococcus belonging to the genus Neisseria found commonly in the upper respiratory tract.It is typically a commensal organism when it is parasitic on oral and nasal mucosa.To our knowledge,it does not cause disease in healthy individuals with normal immunity,but can be pathogenic in those with impaired immune function or change in bacterial colonization site.Neisseria mucosa has been reported to cause bacterial meningitis,conjunctivitis,pneumonia,endocarditis,peritonitis and urethritis.However,peritoneal dialysis-related peritonitis caused by Neisseria mucosa is extremely rare in clinical practice,which has not previously been reported in China.CASE SUMMARY A 55-year-old female presented to the nephrology clinic with upper abdominal pain without apparent cause,accompanied by nausea,vomiting and diarrhea for two days.The patient had a history of Stage 5 chronic kidney disease for five years,combined with renal hypertension and renal anemia,and was treated with peritoneal dialysis for renal replacement therapy.The patient was subsequently diagnosed with peritoneal dialysis-related peritonitis.Routine examination of peritoneal dialysis fluid showed abdominal infection,and the results of microbial culture of the peritoneal dialysis fluid confirmed Neisseria mucosa.Imi-penem/cilastatin 1.0 g q12h was added to peritoneal dialysis fluid for anti-infection treatment.After 24 d,the patient underwent upper extremity arteriovenous fistulation.One month later,the patient was discharged home in a clinically stable state.CONCLUSION Peritonitis caused by Neisseria mucosa is rare.Patients with home-based self-dialysis cannot guarantee good medical and health conditions,and require education on self-protection.
文摘BACKGROUND According to the trend of global population aging,the proportion of elderly patients with chronic kidney disease(CKD)is expected to increase.However,there are more than 20 million people in China with decompensated kidney function,of which 19.25%are elderly people.Therefore,special attention should be paid to the education years,sleep quality,anxiety status,comorbidities with diabetes,cardiovascular disease(CVD),and anemia as independent risk factors for depression in elderly CKD patients.This study explores the clinical management of elderly CKD patients that should address these risk factors to prevent depression and improve their prognosis.AIM To investigate depression risk factors in older patients receiving peritoneal dialysis,aiding future prevention of depression in these patients.METHODS This retrospective study included a primary study population of 170 patients with CKD who received peritoneal dialysis from January 2020 to December 2022.We assessed the patients’mental status using the Beck Depression Inventory Score-II(BDI-II),Self-Rating Anxiety Scale(SAS),Anxiety Inventory Score,and the Pittsburgh Sleep Quality Index(PSQI).Logistic regression was employed to identify depression independent risk factors among these patients.RESULTS The non-depressed group had a significantly longer education period than the depressed group(P<0.05).The depressed group exhibited significantly higher mental status scores than the non-depressed group(P<0.001).Patients with diabetes mellitus(DM)or CVD had a higher probability of developing depression.Patients with depression had significantly lower hemoglobin and albumin levels than patients without depression(P<0.05).Spearman correlation analysis of BDI-II scale scores,measuring depression,indicated positive correlations with BDI-II and SAS scores as risk factors for depression in patients with CKD.In contrast,years of education,hemoglobin levels,and peritoneal Kt/V were negatively correlated,serving as protective factors against depression.An analysis of variance for influences with significant differences in the univariate analysis revealed that years of schooling,BDI-II,SAS,PSQI,DM,CVD,and hemoglobin levels independently influenced depression in older patients with CKD.CONCLUSION Education,BDI-II,SAS,PSQI,DM,and CVD are independent risk factors for depression in older patients with CKD;therefore,post-treatment psychological monitoring of high-risk patients is crucial to prevent depression.
文摘Objective:Bayesian network meta-analysis was used to evaluate the effect of different nursing interventions on the incidence of peritonitis in peritoneal dialysis patients at home.Methods:Cochrane Library,PubMed,Embase,Web of Science,China Biology Medicine disc,CNKI and Wanfang data were searched to identify randomized controlled trials(RCTs)investigating the effects of different nursing interventions or health education on peritonitis in home peritoneal dialysis patients from the establishment of each database to March 2022.After literature screening,the Cochrane 5.1 evaluation tool was used to assess quality,Review Manager 5.4 software was used to generate a literature quality evaluation chart and R4.1.2 software,JAGS package,and GEMTC package were used for statistical analysis.Results:A total of 9 RCTs involving 8 different nursing interventions and a total of 1011 patients were included in the meta-analysis.The incidence of peritonitis for the eight nursing interventions,ranked from highest to lowest,were:systematic nursing,Omaha system case management intervention,routine care+health promotion mode,PD specialist nurse-led multi-disciplinary network platform management mode,5E rehabilitation nursing mode,routine care+Omaha extended nursing service,one-on-one coordinated family support intervention,and routine care.Conclusions:Systematic nursing was found to be the most effective intervention in reducing the incidence of peritonitis in peritoneal dialysis patients at home.However,this conclusion needs to be further verified by more high-quality,multicenter and large sample RCTs.
文摘Objective:To analyze the short-term curative effect of roxadustat in the treatment of renal anemia in patients with peritoneal dialysis.Methods:70 patients with peritoneal dialysis renal anemia admitted to the dialysis department of our hospital from March 2021-March 2023 were selected as research objects,divided into a research group and a reference group according to random number drawing method,with each group consisting of 35 cases.The patients in the research group were treated with roxadustat,and those in the reference group were treated with recombinant human erythropoietin.The total efficacy,anemia index,iron metabolism index,and occurrence of adverse reactions were compared between the two groups.Results:The total efficacy of the treatment received in the research group was significantly higher than that in the reference group(P<0.05).In terms of anemia indicators,there was no statistically significant difference between the hemoglobin(Hb),the red blood cell(RBC),and the hematocrit(HCT)of both groups(P>0.05)before treatment.After treatment,the anemia indicators of the patients in the research group were significantly better than those in the reference group,(P<0.05).In terms of iron metabolism,before treatment,there was no significant difference between the total iron-binding capacity(TIBC),the transferrin(TRF),the ferritin(FER),and iron(Fe)of both groups(P>0.05).After treatment,the research group’s iron metabolism indicators were significantly better than those of the reference group(P<0.05).The incidence of adverse reactions in the research group was significantly lower than that in the reference group(P<0.05).Conclusion:The short-term curative effect of roxadustat in the treatment of peritoneal dialysis patients was demonstrated through this study,making it a viable treatment option.

文摘BACKGROUND Insertion of a catheter into the bladder is a rare complication of peritoneal dialysis(PD),and is mainly related to surgical injury.This paper reports a case of bladder perforation that was caused by percutaneous PD catheterization.CASE SUMMARY A 64-year-old man underwent percutaneous PD catheterization for end-stage renal disease.On the second day after the operation,urgent urination and gross hematuria occurred.Urinalysis showed the presence of red and white blood cells.Empirical anti-infective treatment was given.On the third day after the operation,urgent urination occurred during PD perfusion.Ultrasound showed that the PD catheter was located in the bladder,and subsequent computed tomography(CT)showed that the PD catheter moved through the anterior wall into the bladder.The PD catheter was withdrawn from the bladder and catheterization was retained.Repeat CT on the fourth day after the operation showed that the PD catheter was removed from the bladder,but there was poor catheter function.The PD catheter was removed and the patient was changed to hemodialysis.CT cystography showed that the bladder healed well and the patient was discharged 14 d after the operation.CONCLUSION Bladder perforation injury should be considered and treated timeously in case of bladder irritation during and after percutaneous PD catheterization.The use of Doppler ultrasound and other related technologies may reduce the incidence of such complications.
文摘BACKGROUND The number of end-stage renal disease patients with diabetes mellitus(DM)who are undergoing peritoneal dialysis is increasing.Peritoneal dialysis-associated peritonitis(PDAP)is a serious complication of peritoneal dialysis leading to technical failure and increased mortality in patients undergoing peritoneal dialysis.The profile of clinical symptoms,distribution of pathogenic organisms,and response of PDAP to medical management in the subset of end-stage renal disease patients with DM have not been reported previously.Discrepant results have been found in long-term prognostic outcomes of PDAP in patients with DM.We inferred that DM is associated with bad outcomes in PDAP patients.AIM To compare the clinical features and outcomes of PDAP between patients with DM and those without.METHODS In this multicenter retrospective cohort study,we enrolled patients who had at least one episode of PDAP during the study period.The patients were followed for a median of 31.1 mo.They were divided into a DM group and a non-DM group.Clinical features,therapeutic outcomes,and long-term prognostic outcomes were compared between the two groups.Risk factors associated with therapeutic outcomes of PDAP were analyzed using multivariable logistic regression.A Cox proportional hazards model was constructed to examine the influence of DM on patient survival and incidence of technical failure.RESULTS Overall,373 episodes occurred in the DM group(n=214)and 692 episodes occurred in the non-DM group(n=395).The rates of abdominal pain and fever were similar in the two groups(P>0.05).The DM group had more infections with coagulase-negative Staphylococcus and less infections with Escherichia coli(E.coli)as compared to the non-DM group(P<0.05).Multivariate logistic regression analysis revealed no association between the presence of diabetes and rates of complete cure,catheter removal,PDAP-related death,or relapse of PDAP(P>0.05).Patients in the DM group were older and had a higher burden of cardiovascular disease,with lower level of serum albumin,but a higher estimated glomerular filtration rate(P<0.05).Cox proportional hazards model confirmed that the presence of diabetes was a significant predictor of all-cause mortality(hazard ratio=1.531,95%confidence interval:1.091-2.148,P<0.05),but did not predict the occurrence of technical failure(P>0.05).CONCLUSION PDAP patients with diabetes have similar symptomology and are predisposed to coagulase-negative Staphylococcus but not E.coli infection compared those without.Diabetes is associated with higher all-cause mortality but not therapeutic outcomes of PDAP.
文摘AIM: To compare the prevalence and diversity of gastrointestinal (GI) symptoms in patients undergoing peritoneal dialysis (PD) and hemodialysis (HD).
文摘In this paper,the experience in the treatment of complications due to continuousambulatory peritoneal dialysis for chronic renal failure with traditional Chinese medicine(TCM)is reported.Modified Renshen Yangrong Tang(Ginseng Nutrition Decoction)wasused for anorexia and hypoproteinemia;modified Xiangsha Liujunzi Tang(Decoction ofCyperus and Amomum with Six Noble Ingredients)for abdominal pain and distension;modified Da Chaihu Tang(Major Bupleurum Decoction)for peritonitis;modifiedShenling Baizhu San(Powder of Ginseng,Poria and Atractylodes)for diarrhea due toinsufficiency of the spleen with abundance of dampness;Lizhong Tang(Decoction forRegulating the Function of Middle-jiao)and modified Sishen Wan(Pills of FourMiraculous Drugs)for insufficiency of both the spleen and the kidney;Siwu Tang(Decoction of Four Ingredients)added with other drugs for cutaneous pruritus,andGuishao Sijunzi Tang(Decoction of Four Noble Drugs added with Chinese Angelica Rootand white Peony Root)for renal anemia.The therapeutic principles of invigorating theliver and kidney,strengthening the bones and muscles,and promoting blood circulation toeliminate blood stasis were adopted in the treatment of renal osteopathy,and thetherapeutic principles of invigorating the liver and kidney,expelling phlegm and resolvingdampness,and promoting blood circulation to eliminate blood stasis in the treatment ofhyperlipemia.Shen Tekang capsules(capsules for improving the renal function)wasadministered to patients for strengthening the viability and improving the nutrition state,and the recipe for treating renal function failure(both formulated by the authors)forimproving the renal function so as to decrease the frequency and duration of dialysis.
文摘AIM: To investigate gastrointestinal (GI) symptoms in peritoneal dialysis (PD) patients and to explore related factors contributing to GI symptoms. METHODS: One hundred and twelve patients undergoing PD participated in the study. The gastrointestinal symptom rating scale was used for measuring GI symptoms. Information on age, height, weight, body mass index, disease leading to chronic renal failure, history of corticosteroid therapy, presence of predialytic GI symptoms, daily dosage of pills, and duration, type and daily dialysate volume of PD was obtained by interviewing patients and/or reviewing the medical records. Hemoglobin, albumin and Kt/V data were obtained from follow-up database. We used multiple regression analysis with stepwise backward variable selection to test for factors predicting GSRS scores with significance level of selection entry at 0.05 and selection of stay at 0.10. RESULTS: The prevalence of eating dysfunction, reflux and indigestion in the PD patients was 44.2%, 32.7%,32.7%, respectively. A history of corticosteroid therapy (b = 8.93, P < 0.001) and all pills daily intake (b = 0.16, P = 0.007) were positively correlated to GI symptoms, while residual renal Kt/V (b =-3.47, P = 0.009) was negatively correlated to GI symptoms. Other factors were proven to be not associated with GI symptoms, with P > 0.05. CONCLUSION: Eating dysfunction, reflux and indigestion were common in PD patients. Daily dosage of pills and corticosteroid history predicted GI symptoms, while residual renal function prevented them.
文摘Peritoneal dialysis (PD) is associated with a high risk of infection of the peritoneum, subcutaneous tunnel and catheter exit site. Although quality standards demand an infection rate 〈 0.67 episodes/patient/year on dialy-sis, the reported overall rate of PD associated infection is 0.24-1.66 episodes/patient/year. It is estimated that for every 0.5-per-year increase in peritonitis rate, the risk of death increases by 4% and 18% of the episodes resulted in removal of the PD catheter and 3.5% re-sulted in death. Improved diagnosis, increased aware-ness of causative agents in addition to other measures will facilitate prompt management of PD associated infection and salvage of PD modality. The aims of this review are to determine the magnitude of the infection problem, identify possible risk factors and provide an update on the diagnosis and management of PD as-sociated infection. Gram-positive cocci such as Staphy-lococcus epidermidis , other coagulase negative staphy-lococcoci, and Staphylococcus aureus (S. aureus ) are the most frequent aetiological agents of PD-associated peritonitis worldwide. Empiric antibiotic therapy must cover both gram-positive and gram-negative organ-isms. However, use of systemic vancomycin and cip-rofoxacin administration for example, is a simple and efficient first-line protocol antibiotic therapy for PD peritonitis - success rate of 77%. However, for fungal PD peritonitis, it is now standard practice to remove PD catheters in addition to antifungal treatment for a minimum of 3 wk and subsequent transfer to hemodi-alysis. To prevent PD associated infections, prophylactic antibiotic administration before catheter placement, adequate patient training, exit-site care, and treatment for S. aureus nasal carriage should be employed. Mupi-rocin treatment can reduce the risk of exit site infection by 46% but it cannot decrease the risk of peritonitis due to all organisms.

文摘Long-term exposure to bioincompatible peritoneal dialysis(PD) solutions frequently results in peritoneal fibrosis and ultrafiltration failure,which limits the life-long use of and leads to the cessation of PD therapy.Therefore,it is important to elucidate the pathogenesis of peritoneal fibrosis in order to design therapeutic strategies to prevent its occurrence.Peritoneal fibrosis is associated with a chronic inflammatory status as well as an elevated oxidative stress(OS) status.Beyond uremia per se,OS also results from chronic exposure to high glucose load,glucose degradation products,advanced glycation end products,and hypertonic stress.Therapy targeting the cannabinoid(CB) signaling pathway has been reported in several chronic inflammatory diseases with elevated OS.We recently reported that the intra-peritoneal administration of CB receptor ligands,including CB_1 receptor antagonistsand CB_2 receptor agonists,ameliorated dialysis-related peritoneal fibrosis.As targeting the CB signaling pathway has been reported to be beneficial in attenuating the processes of several chronic inflammatory diseases,we reviewed the interaction among the cannabinoid system,inflammation,and OS,through which clinicians ultimately aim to prolong the peritoneal survival of PD patients.
文摘Congestion is an integral component of cardiorenal syn-drome and portends an adverse impact on the outcomes. Recent studies suggest that congestion has the ability ofmodulating the interactions between the kidney and the heart in this setting. Peritoneal dialysis (PD) is a home-based therapeutic modality that is not only offered to patients with end-stage renal disease to provide solute clearance and ultrafltration, but it has also been used in patients with refractory heart failure and fuid overload to help optimize volume status. Several uncontrolled studies and case series have so far evaluated the role of PD in management of hypervolemia for patients with heart failure. They have generally reported favorable results in this setting. However, the data on the outcomes of patients with end-stage renal disease and concomitant heart failure is mixed, and the proposed theoretical advantages of PD might not translate into improvedclinical endpoints. Congestion is prevalent in this patient population and has a signifcant effect on their survival. As studies suggest that a significant subset of patients with end-stage renal disease who receive PD therapy are hypervolemic, suboptimal management of congestion could at least in part explain these conficting results. PD is a highly fexible therapeutic modality and the choice oftechniques, regimens, and solutions can affect its ability for optimization of fluid status. This article provides an overview of the currently available data on the role and clinical relevance of congestion in patients with cardiorenal syndrome and reviews potential options to enhance decongestion in these patients.
文摘A major concern inhibiting some clinicians from embracing peritoneal dialysis(PD) as the preferred first modality of dialysis is the effects of PD solutions on the peritoneal membrane. These anatomical and functional changes predispose to complications like peritonitis,encapsulating peritoneal sclerosis and ultrafiltration failure. In recent years, "biocompatible" and glucosesparing PD regimens have been developed to minimize damage to the peritoneal membrane. Can the use of these more expensive solutions be justified on current evidence? In this review of the literature, we explore how we may individualize the prescription of biocompatible PD fluid.
